The genus Chelone is comprised of a handful of perennials from North America grown for their sturdy dispositions and white, pink, or purple flowers that resemble turtle heads. The spikes of tubular, 2-lipped flowers bloom late in the summer to the middle of autumn. Chelone work well in a damp border, bog garden, shade garden, or at waterside.
